Chemotactic predator-prey dynamics [PDF]

Physical Review E, 2010
A discrete chemotactic predator-prey model is proposed in which the prey secrets a diffusing chemical which is sensed by the predator and vice versa. Two dynamical states corresponding to catching and escaping are identified and it is shown that steady ...

Tearing Out the Income Tax by the (Grass)Roots [PDF]

Landscape Ecology, 2011
Landscapes are increasingly fragmented, and conservation programs have started to look at network approaches for maintaining populations at a larger scale. We present an agent-based model of predator–prey dynamics where the agents (i.e.

A Microfoundation of Predator-Prey Dynamics [PDF]

Natural Resource Modeling, 2003
Predator-prey relationships account for an important part of all interactions between species. In this paper we provide a microfoundation for such predator-prey relations in a food chain.

Cascade of Complexity in Evolving Predator-Prey Dynamics [PDF]

Physical Review Letters, 2007
We simulate an individual-based model that represents both the phenotype and genome of digital organisms with predator-prey interactions. We show how open-ended growth of complexity arises from the invariance of genetic evolution operators with respect ...

COMPUTATIONAL COMPLEX PREDATOR-PREY DYNAMICS [PDF]

bioRxiv, 2017
ABSTRACTTwo species predator-prey with stage structure of mature and immature mathematical models are studied over the last few decades.Xin-an Zhang et alstudied a mathematical model with stage structure of two species in 2010. In this article, an attempt has been made to comprehend the coupled predator-prey dynamics with mature-immature stage ...

Mathematical Analysis of Discrete Fractional Prey-Predator Model with Fear Effect and Square Root Functional Response

Cumhuriyet Science Journal, 2022
This paper investigates the dynamics of a discrete fractional prey-predator system. The prey-predator interaction is modelled using the square root functional response, which appropriately models systems in which the prey exhibits a strong herd structure,

Translating Virtual Prey-Predator Interaction to Real-World Robotic Environments: Enabling Multimodal Sensing and Evolutionary Dynamics

Biomimetics, 2023
Prey-predator interactions play a pivotal role in elucidating the evolution and adaptation of various organism’s traits. Numerous approaches have been employed to study the dynamics of prey-predator interaction systems, with agent-based methodologies ...

A two-patch prey-predator model with predator dispersal driven by the predation strength

Mathematical Biosciences and Engineering, 2017
Foraging movements of predator play an important role in population dynamics of prey-predator systems, which have been considered as mechanisms that contribute to spatial self-organization of prey and predator.

Predator-Prey in Tumor-Immune Interactions: A Wrong Model or Just an Incomplete One?

Frontiers in Immunology, 2021
Tumor-immune interactions are often framed as predator-prey. This imperfect analogy describes how immune cells (the predators) hunt and kill immunogenic tumor cells (the prey).

Bistability induced by generalist natural enemies can reverse pest invasions [PDF]

, 2016
Reaction-diffusion analytical modeling of predator-prey systems has shown that specialist natural enemies can slow, stop and even reverse pest invasions, assuming that the prey population displays a strong Allee effect in its growth.
